Hi All,
The following series updates the PRU remoteproc driver to support the
PRU, RTU and Tx_PRU cores present within the ICSSG IP on AM64x SoCs.
Patches are on top of latest rproc-next branch based on v5.13-rc1,
commit 30da589dba53 ("dt-bindings: remoteproc: qcom: pas: Fix indentation
warnings").
There are some minor differences around the PRU cores like different
Broadside RAM (BSRAM) sizes, but otherwise behave functionally the same
as the PRU cores on previous SoCs.
regards,
Suman
